How to delete the {} in the textbox?

Question

I'm trying to program a restaurant menu and after a customer's choice, it will display the overall total of the order. My problem is that when I ran the code, there's a {} in the textbox. How can I delete it?

Here is the image:

Here is my full code. Please do give me some advice on how to improve it.

Answer 1

I'm assuming that the {} in your output is actually ().

final = message, "Total:        $", str(float(total))

should be

final = message + "Total:        $" + str(float(total))

The reason it happened is that by using commas, you created a tuple of three strings rather than a single string, and the default representation of a tuple has parentheses around it.

Answer 2

final = message, "Total:        $", str(float(total))

instead of use string concatenation

final = message + "Total:       %s $"%str(float(total))
